About our thermal roof survey in Northchurch
Wet insulation under a flat roof covering holds heat for longer than dry. So a wet patch can show as a warmer or cooler area on the camera. It helps us see how far water may have spread under the covering, which is hard to judge by eye. We then check those areas with moisture readings. If you’ve noticed missing or slipped insulation and possible trapped moisture under a flat roof covering, a survey will tell you what’s going on.
Around Northchurch, a good many roofs are low enough to see partly from the garden or the street. The parts you cannot see, such as rear slopes, valleys and chimney tops, are where a drone or thermal camera adds detail. Both depend on the weather on the day. Even so, a close-up image frequently shows wear on ridges and flashings that a view from ground level misses.
How fast the report arrives depends on the package: Basic within 48 hours, Standard in 24–48 hours and Premium the same day.

Thermal roof surveys in Northchurch: local notes
Across the South East, older homes tend to have slate or clay tiles, and many later ones concrete tiles, and flat-roofed additions turn up almost everywhere. Where a roof is steep, tall or hard to see from ground level, drone photos and thermal images add detail. If your survey includes the drone, we check the Drone Safety Map for restrictions before flying.
If you look after a building such as St Mary's CofE Primary School, big roofs are where close-up aerial shots and thermal images show the most at once. Cholesbury Manor House, about 3 miles west, is one of the historic houses in the wider area around Northchurch. Photos from the air and thermal images let an old roof be checked without anyone disturbing it. Take an older house close to Church of Saint Mary: thin or patchy insulation under an old roof often shows up clearly on a thermal image.
Northchurch is about 1 mile north-west of Berkhamsted, in Hertfordshire. Whether the building in Northchurch is a house, a flat or a commercial unit, the roof can be surveyed on a weekday or at the weekend. Our area takes in places right across Hertfordshire.

Leave it or get it looked at?
Repeated repairs that don’t stop a leak are a sign the source hasn’t been traced. Thermal imaging with moisture readings can help narrow it down, instead of trying repair after repair. In an older home around Northchurch, water from a roof defect can get into timber and plaster, and that’s a much bigger job than the original defect.
Prices start from £400, including VAT. Packages run from Basic at £150 through Standard at £250 to Premium at £400, including VAT.

How it works
The aim of the visit is simple: to look at the roof as closely as is safe and record what we find. Everything we note and photograph goes into the written report. The visit normally takes between one and two hours for most homes, plus time to check any thermal findings with moisture readings. For a survey in Northchurch, we agree the time, the access and parking before the day. Weekday and weekend visits are both possible. If there are outbuildings or garages you want looked at, mention them.
- You let us know about the roof and any damp, leaks or cold rooms.
- The weather and surface conditions are recorded.
- We inspect the roof and take thermal images during the same visit.
- We back up the thermal patterns with moisture readings.
- The Premium report reaches you the same day, and we go through it with you in person.
Getting ready for the survey
- Let us know about any leaks, stains or damp patches you know of
- Leave side gates unlocked
- Buyers: confirm access with the estate agent or seller

Related advice
Before and after the survey
You don’t need to be a roofer to help. What helps most:
- Remember the conditions on the day affect the results
- Clear leaves from outlets and gutters each autumn
- Photograph damp patches with the date
- Move stored items away from the loft hatch
Many people send the report to roofers, who can then quote for the areas shown. Each thermal image is matched to a normal photo, so the areas are easy to locate.
Check that loft insulation is laid evenly and hasn’t been pushed aside. Gaps often appear after work in the loft.

Single-ply and EPDM roofs
Thin membranes can show patterns from the layers beneath. Reflections from shiny surfaces can affect readings, which we allow for.

In the roof space, the camera can pick up gaps and thin areas of insulation. We look where there’s safe access.

Does a conservation area affect roof work in Northchurch?
For listing, use Historic England’s list; for conservation areas, ask the council. The answer matters most when a change of material is on the cards.

Surveys can be booked for any day of the week: weekdays, Saturdays and Sundays. Just let us know the days that suit you.
Which survey includes thermal imaging?

Can you tell me if my roof has asbestos?
No. We can flag materials that might contain asbestos, but confirming it is a job for a specialist asbestos surveyor. It may be present in buildings built or refurbished before 2000.

Can I check my roof myself?
What you can’t do safely is get up close. Slates, tiles, flat roofs and rooflights can give way, and falls from height are serious. That is where a survey comes in.
It helps to keep a record: dates of leaks, photos from ground level and any work done on the roof. Send it with your enquiry.
